The tables below presents some characteristic ways1. people use the four mental functions or mental processes of the MBTI Personality Type model. They are arranged in pairs of polar opposite concepts and under the particular mental function they are associated with. Read them to determine which of the opposites of each pair is most inherently characteristic of you (i.e. your natural bent vs. what wisdom or experience may have taught you). Remember it is OK and normal to have "some" characteristics that are opposite your favored preference ( as is it is OK and normal to have none that are opposite).

Click the radio button of the opposite of each pair that best fits. (Doing so will simply serve as a visible checklist to help you get acquainted with some trait correlates of these four mental functions; the checked boxes do not automatically score any test. (Persons seeking a scientifically pedigreed assessment like this are urged to seek out a qualified MBTI practitioner who has the credentials to administer an MBTI Step 2 Assessment)

Based upon what you understand about the 4 mental functions (S, N, T & F) [For a review you might want to re-read the Introduction to Type page. Click here to bring it up in a separate window] and a review of the selections you've just made above, consider which of the four mental functions (S, N, T or F) may be your most fundamental guiding preference, your Dominant Mental Function. (Some may find it helpful to talk over these considerations out loud and/or with another person.)

Does this square with what the Hierarchy Table suggests is the #1 function for people of your type? If not, it may be an indicator you are atypical for your type. Or it may signal that a different type might be a better fit for you.

1.The above material was adapted from the work of David R. Saunders, Ph.D. who performed the initial psychometric research on trait correlates of the MBTI from "test" questions that Myers employed over several years in her endless quest to broaden the base of Type knowledge. Saunders research eventually resulted in the development of the "Type Differentiation Indicator" and the "Expanded Analysis Report." His work was later extended by others, re-constituted, and updated into what is now known as the Step II and Step III MBTI Personality Assessments published by CPP, Inc.

I like this booklet by Nardi and Berens. About 50 pages, reasonable price, and an easy read for the person wishing to better understand his or her personality type . . . and the overall concepts surrounding Personality Types. [Ordering Info Here]
